I want to move each point in different directions

Hi there, I want to make a “star” shape. In that case I was wondering how to move the mid-points of each lines in different directions.

here is one of many ways…

Yeah, you asked for inerpolated curve…Use Interpolate Curve instead.

…or like this with more consistent tangencies

The blue groups highlight some parametric options that are well worth exploring. :sunglasses:

Thank you so so much for all of your replys :heart_eyes:

Like towers, this is a project that many beginners could find useful as a GH learning exercise.

The number of parameters in my previous post is a bit absurd, of course, but let’s throw in a few more, just for fun. Manually created points as you supplied is actually a new wrinkle; you can also start with a regular polygon:

To handle your manually created points, I used Plane Fit and Sort Along Curve, which has a curious side effect. It’s perfectly happy with “3D” points that are not in the same plane. The “Random” Box can be dimensioned as a 3D space or as a flat surface on the XY, XZ or YZ plane.

Useful? Maybe not. Good practice though.


Thanks for ur suggestions :heart_eyes:
